“…the scattering of stable and unstable projectiles [62,63,[67][68][69][70][71][72][73][74][75][76][77][78][79][80]. Here the interactions between 30 Ne and 12 C and between n and 12 C are constructed with the DFM with the Melbourne g-matrix, and the potential between 30 Ne and n is made with the well-depth method; see Refs.…”

The deformation of Ne isotopes in the island-of-inversion region is determined by the doublefolding model with the Melbourne g-matrix and the density calculated by the antisymmetrized molecular dynamics (AMD). The double-folding model reproduces, with no adjustable parameter, the measured reaction cross sections for the scattering of 28−32 Ne from 12 C at 240MeV/nucleon. The quadrupole deformation thus determined is around 0.4 in the island-of-inversion region and 31 Ne is a halo nuclei with large deformation. We propose the Woods-Saxon model with a suitably chosen parameterization set and the deformation given by the AMD calculation as a convenient way of simulating the density calculated directly by the AMD. The deformed Woods-Saxon model provides the density with the proper asymptotic form. The pairing effect is investigated, and the importance of the angular momentum projection for obtaining the large deformation in the island-of-inversion region is pointed out.

“…This single-particle picture has been extensively used in the literature to explain also reactions induced by this nucleus (see, for instance, Refs. [20,32,33]). However, there are also numerous experimental and theoretical findings that these low-lying states of 11 Be contain significant admixtures of core-excited components [12,[34][35][36].…”

The quantum description of a particle moving in a deformed potential is investigated. A pseudostate (PS) basis is used to represent the states of the composite system. This PS basis is obtained by diagonalizing the system Hamiltonian in a family of square integrable functions. In this work the transformed harmonic oscillator (THO) functions, obtained from the solutions of the harmonic oscillator using a local scale transformation (LST), are used. The proposed method is applied to the 11 Be nucleus, treated in a two-body model ( 10 Be + n). Structure observables have been studied. Wave functions and energies obtained for the bound states and some low-lying resonances are compared with those obtained by direct integration of the Schrödinger equation. The dipole and quadrupole electric transition probabilities for the low-energy continuum have been calculated in the THO basis, and compared with the exact distributions obtained with the scattering states.

“…A second bump was also observed at E x = 3.41 MeV, which was given a tentative assignment of 3/2 + , with a small contribution of the d 3/2 wave coupled to 10 Be(0 + ) and a larger contribution of the 10 Be(2 + ) ⊗ ν2s 1/2 configuration. As in previous analyses of this reaction [33,34], we use a two-body model of the projectile, 11 Be = 10 Be(g.s.) + n, and hence those states based on the core excited states are absent from our model space.…”

Exploring continuum structures with a pseudo-state basis

The ability of a recently developed square-integrable discrete basis to represent the properties of the continuum of a two-body system is investigated. The basis is obtained performing a simple analytic local scale transformation to the harmonic oscillator basis. Scattering phase-shifts and the electric transition probabilities B(E1) and B(E2) have been evaluated for several potentials using the proposed basis. Both quantities are found to be in excellent agreement with the exact values calculated from the true scattering states. The basis has been applied to describe the projectile continuum in the 6 He scattering by 12 C and 208 Pb targets at 240 MeV/nucleon and the 11 Be scattering by 12 C at 67 MeV/nucleon. The calculated breakup differential cross sections are found to be in very good agreement with the available experimental data for these reactions.
